A projector is a device that projects an image or video onto a screen or surface. It typically uses a light source, lens, and other components to display the image in a larger size.
A screen board, also known as a projection screen, is a flat surface that is specifically designed to reflect the projected image back to the viewer. It can be made of various materials such as fabric, vinyl, or glass, and comes in different sizes and types, such as fixed frame screens, motorized screens, or portable screens. The screen board is essential for providing a clear and sharp image for the audience to view.

Projector
- A device that uses lenses to project an enlarged image or video onto a screen or surface.
- Types:
- LCD (Liquid Crystal Display): Uses liquid crystals to modulate light and create the image.
- DLP (Digital Light Processing): Uses micromirrors to reflect light and create the image.
- LED (Light Emitting Diode): Uses LEDs as the light source, offering high brightness and durability.
Screen Board
- A surface designed to display the projected image in a clear and visible manner.
- Types:
- Whiteboard: A smooth, non-reflective surface that can be used for writing or dry-erase markers.
- Projector Screen: A dedicated screen specifically designed for displaying projections, featuring high-quality materials and coatings for optimal image clarity and brightness.
- Silver/Gray Screen: A screen with a reflective surface that enhances contrast and color accuracy.
- Coatings:
- Matte: Non-reflective surface, suitable for most uses.
- Glossy: Reflects light, providing a higher brightness but also reducing image contrast.
- Pearl: Combines matte and glossy characteristics for a balanced image.
